UNF Nature Perserve

Thursday, February 4, 2016

My class went to UNF. I learned that a little stream can go all the way to the intercostal and that a river can be so pretty and turtles need sun light to digest food. I already knew that you can tell how old a tree is by counting the rings on the stump. I also knew that a cypress tree can live for a long time. did you know that you can build a fort out of a tree? Well you can.

    In the wild, turtles and tortoises are exposed to ultraviolet light (UV) every day. Absolutely essential to their health and growth, UV plays a key role in the production of Vitamin D3, which is necessary in the absorption and metabolism of calcium, as well as other essential vitamins and minerals. Vitamin D3 deficiency can result in limited shell growth, metabolic bone disease, and often, a premature death.
    Each species of turtle/tortoise may have different Vitamin D requirements. The need for Vitamin D depends upon whether the turtle/tortoise is a land or water species, whether he is an herbivore (eats plants) or carnivore (eats meat), and upon his geographical origin (temperate or tropical).
